Three's a charm : The title compound (see picture, right, WO 6 purple polyhedra, Mn orange and brown, Si green, O red) contains an embedded mixed‐valence {Mn 5 O 6 } cubane core, which is structurally similar to the active site in photosystem II. Solid‐, solution‐, and gas‐phase studies indicate the presence of three lacunary Keggin fragments, thereby giving insight into the complex solution chemistry of plenary POM fragments.
